为提高分扭传动系统的均载性能和传动稳定性,针对某单输入双输出齿轮分扭传动系统,基于对称、同步变化和随动思想,建立了齿轮分扭传动系统的3种联动中心距误差计算模型,推导了该误差在啮合线上的投影计算公式,研究了基于3种联动中心距误差分配对系统均载和动载荷系数的影响。结果表明,中心距误差对均载系数和动载系数的影响较小;3种不同计算模型下的偏转角对系统均载系数和动载系数影响较大,尤其是同步变化和随动变化模式。从计算结果来看,采用对称变化的误差分布模型,误差有较大的选择分布空间,可采用该种误差分布模式获得圆柱齿轮分扭传动系统的良好动态性能。
In order to improve the load sharing performance and transmission stability of the split torque transmission system, aiming at a single input double output gear torque transmission system, three kinds of linkage center distance error calculation models of a single-input double-output gear split torque transmission system are established based on the idea of symmetry, synchronous change and follow-up. The projection calculation formula of the error on the meshing line is derived, and the influence of distribution of three kinds of linkage center distance error on the system load sharing and dynamic load coefficient is studied. The results show that the center distance error has little influence on the load sharing coefficient and dynamic load coefficient. The deflection angle under three different calculation models has a great influence on the system load sharing coefficient and dynamic load coefficient, especially the synchronous and follow-up change modes. From the calculation results, using the symmetrical error distribution model, there is a large choice of distribution space for error, which can be used to obtain the good dynamic performance of the cylindrical gear transmission system.
